please update rust compiler to latest stable version

keeferrourke commented 5 years ago

This is done using the latest available versions of rustc and cargo on Ubuntu 18.04..

expl0ratory commented 5 years ago

Latest on ubuntu 18.04 is 1.25, this requires 1.27, so you must ignore ubuntu, and install manually using https://www.rust-lang.org/en-US/ unfortunately

I take it back, it doesn't work in 1.27 either

sorry, i don't support specific distributive rustc. Only requirement is use stable version. It is easy can be installed with rustup.
